command line args

I am trying to print command line arguments one per second. I have this

while [ $# -gt 0 ]
do

echo "6"
shift
echo "5"
shift
echo "4"
shift
echo "3"
shift
echo "2"
shift
echo "1"
shift

done

but when i run it like this it just prints them all at once:
6
5
4
3
2
1

and I want a 1 second pause between numbers.

Anyone?
